My Compaq Presario R3057EA hangs during ACPI initialization. The last
message is "Executing all Device _STA and _INI methods". git bisect
told me that:

[PATCH] x86-64: i386/x86-64: Fix time going twice as fast problem on ATI Xpress chipsets

Original patch from Bertro Simul

This is probably still not quite correct, but seems to be
the best solution so far.

Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Passing enable_timer_pin_1 as a kernel boot parameter doesn't help,
but this patch does:

diff --git a/arch/i386/kernel/io_apic.c b/arch/i386/kernel/io_apic.c
--- a/arch/i386/kernel/io_apic.c
+++ b/arch/i386/kernel/io_apic.c
@@ -2213,8 +2213,6 @@ static inline void check_timer(void)
setup_nmi();
enable_8259A_irq(0);
}
- if (disable_timer_pin_1 > 0)
- clear_IO_APIC_pin(0, pin1);
return;
}
clear_IO_APIC_pin(0, pin1);
But doing that is equivalent to reverting the whole patch, so it's
probably not the right solution. My computer has an Intel P4 CPU, ie
it's not x86_64.
